Created "file" and can't access it?

Created some documents of type "file" on the siteframe server that I administer, and they seemed to be created OK. But I get "forbidden" (access denied) messages from the web server when I try to download the file. I can get a folder listing of .../files (is that supposed to be allowed?), and even .../files/0005 say, for user ID 5 (who has created a "file" document), but not for my own user ID. How can that come to be? I've tried this both logged in as a normal user and as admin. Same results. Both folders are forbidden even to admin. This is on Siteframe 3.2 Thanks.

folder permissions 750 vs 755

Followup: Checked the user folders under .../files/ using a "file manager" (i.e. outside of Siteframe) and saw that their permissions are "750", i.e., "group" read, no access to "world". That was the case both for folders I could access and those I could not access. Changed one of those that I could not access to 755 (world allowed to read/exec) and then I could access it. But that does not explain why I could access some other ones with "750" permissions, nor why is Siteframe creating folders for users' files with this permission setting? And what does "group" mean in this context? Thanks for any help.
